XVILLIAM H. KELLY, OF NEW YORK, N. Y.

ROTARY BLOTTER.

SPECIFICATION forming part of Letters Patent No. 571,862, dated November24, 1896, Application filed January 16, 1896. Serial No 575,706. (Nomodel.)

To all whom it may concern:

Be it known. that I, \VILLIAH H. KELLY, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Rotary Blotters;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it a-ppertains to make and use the same.

Myinvention relates to improvements in rotary blotters, and it has forits object, among other things, to prevent the blurring ofheavily-shaded inklines heretofore incidental to this class of blotters;and it consists, primarily, of the detailed construction of the partssubstantially as hereinafter more fully disclosed, and specificallypointed out by the claim.

In the drawings, Figure 1 is a side view of the blotter, theblotting-paper and cushion being shown as yielding to the pressure ofthe roller as it passes over the paper to be blotted. Fig. 2 is a planview of the blotter, showing a portion of the blotting-paper removed toreveal the method of fastening the two ends of the cushion to theroller, a portion of the handle being broken off. Fig. 3 is a side viewof the blotter, showing the twopart roller as unlatched and swung openpreparatory to the insertion of the strip of blotting-paper, the handlealso being shown as broken off. Fig. 4: is a side View of a portion ofthe blotter, showing a modified form of latch for securing the two partsof the roller when closed. 5 is an enlarged side View of a portion ofthe blotter, showing another modified form of latch; and Fig. 6 is a topplan VIEW of the modification shown in Fig. 5, a portion of the latchbeing shown in sectionv cut through line 6 6 of Fig. 5.

In all rotary blotters heretofore used the cylinder surrounded byblotting-paper has presented a rigid unyielding surface. As a result,the roller as'it passed over the ink on the paper to be blotted has hada tendency to push along and blur the superfluous ink on heavily-shadedlines instead of permitting the blotting-paper to yield and properlyabsorb the ink.

To avoid this defect, the following-described device has been invented,like letters of reference indicating like parts.

To the handle A is attached a bracket B, the outer ends of which formbearings for trunnions C, constructed on cross'plates D D, attached tocylinder E. This cylinder is longitudinally bisected into parts F and G.Part F of the cylinder is rigidly connected .to the cross-plates bymeans of nails or screws ff. Part G of the same is hinged at or near oneof its edges at g, and is provided at aconvenient distance from itsopposite edge with a latch-pin 71.. Latch II is constructed on thecross-plate D in such a manner as to admit of its engagement with pin72. when the two parts of the cylinder are closed. This latch mayconsist of a pivoted hooked arm, as shown in Figs. 1, 2, and 3, or itmay be provided with a spring-hook, as shown in Fig. 4, or afriction-recess, as shown in Figs. 5 and (3. V

Tothe ou ter surface of the two-part cylinder is attached a single stiffpaper or light metal yielding cover I by means of tacks i i1, driventhrough the edge of the cover into the cylinder in close proximity tothe edges of the two parts of the cylinder which form the slot or mouth6 when the parts are closed to form the cylinder, as shown in Figs. 1,2, 3, and 5. The width of this cover is equal to the length of thecylinder, while the length thereof is suliieiently in excess of thecircumference of the cylinder when closed as to admitof an open space Kto exist between the inner surface of the cover and the outer surface ofthe cylinder.

A strip of blotting-paper L is provided equal in widthv to that of thecover and of sufficient length to admit of iis two ends I l to be foldedover the edges of the two parts of the cylinder which form the mouth 6after the blotting-paper has been drawn tautly over the cover I.

In adjusting the blotting-paper to the cylinder the part G of thecylinder is unlatched and thrown open, as shown in Fig. The strip ofblotting-paper is then snugly placed over the cover I and the endsthereof folded over the open edges of the parts F and G of IOO thecylinder. The part G is then closed and latched, the edges of the twoparts of the cylinder Which form the mouth firmly clamping the paper inplace.

The open space K, formed by the cover and cylinder, as hereinbeforedescribed, causes the cover I to act as a yielding cushion, and as theblotter is rolled over the paper to be blotted the blotting-paper ispermitted to yield at its point of impact and in a measure to conform tothe fiat surface of the paper to be blotted, as shown at M, Fig. 1, thuspresenting an increased blotting-surface, and thereby completelyabsorbing all superfluous ink.

Having thus described my invention, What moist or I claim as new, anddesire to secure byLetters Patent, is-

In a rotary blotter the combination of the handle and connections as setforth with a two-part cylinder, a yielding cover attached at its ends tothe edges of the cylinder and a strip of blotting-paper folded at itsends and securely held in place in the manner described.

In testimony whereof I affix my signature in presence of two Witnesses.
